GLASS-GATHERING MECHANISM Specification of Letters Patent.

To allwhom it may concern:

Be it known that I. AUeus'r Ka'now, a citizen of the United States, residing at Toledo in the county ot Lneas and State of Ohio, have invented certain new and useful Improrements in Glass-Gathering l\Ieehanism, otu'hich the following is a specification.

My invention relates to machinery for mamifacturing glass articles, and more particularly to a mechanism forgatheriug' the glass and forl'i'iii'ig the same into blanks suitable for hlou'ing or other treatment neces ,sary for the production of the finished article.

The invention may be regarded as an improvement upon or modification of .the machine shown in my lo-pending application SerialNo. 570,621 filed July 6,1910, and in h 222 of 1911,:115. though the construction and arrangements constituting the present invention are sits ceptihle, of employment in apparatus some-- what different in its design and organization from that shown in said application.

The type of glass forming machine with which this invention is concerned. comprises .a rotating structure prouided with one or more glassgatheriug units which are period ieally brought to a point opposite the \rorking opening of a stationary glass furnace and are thrust into said opening to make the successive gathers. lVhen-the blanks have been formed in this \raythey are delivered to. spindles, or other mechanisms, for fur- :ther treatment, said devices being preferahly carried on the same rotating structure" which supports the gathering I mechanisms so thatjthe manufacture of the articles is completed -by a series ofautomatic opera tions which are carried out by difi'erent'parts 'of'a single machine.

In the glass tary movement of the ramor gathering device is arrested during the periods when the ram th ru st into. and with drawn from, the furnace,

The prineiprl (d ier-t of my present invention is to fi litl l a simplification of the-gathering: apparan s. in a machine of thislreneral type. by 1 roriiliu a gatheringmechanism ami ram lor operating! the same, so constructed that: t. in {rather is made without in tel-ru ning th continuous rotary move ment: of the ram and also without arresting; the movement of rotation of the supporting structure. 4 i l 'lhe inrenlir n is illustrated in apre'l'erred embodiment.il the :u-cmnpanying drawings wherein- Figure l shows, in elevation, the upper portion of a glass-forming machine otthe type with which my present invention is concerned. together with a portion of the glass furnacefrom which the gather vis made. the lath r lacing in section.

Fig. 2 is a radial sectional View, with parts in elevation, illustrating the constructioiro'f the in heriui! ram and its actuating mechanisms. i

Fig. 3 is a iew, in perspective, of one of the slides forning part of said actuating mechanism, ald

Fig. 4 is a plan view of the ram and associated parts, a lrtaiu structures, not relevant to the present invention, being omitted for he purpose '0 clearness of illustration.

' Like chara :ters of reference designate 'like parts in t' ieseveral figures of the drawrugs. I Inasmuch a: many 0t thedetaiis of construction of he machine considered as a whole, which are necessarily shown in the drawings, hare no hearing upon my present invention, the description will he limited to such portions of the machine as require description for, an' understanding of the improvement he e concerned.

Referring t i the draivings, 10 designates a rotary struotr re' adapted to support a numher of glass :athering units, to he -hereinafter describe 1. This structure is shown as carrying ads; I a plurality, of "s'pi ulles 11 which-"ape; a'franged to receive the glass blanks after they havefbengathered and formed. 12 it". glass fhrnace whichis stationary and is provided with a working opening 13. Fixed to aplate 14 forming 'lnovenientby part of the rotary strtlcture. 10, is an inclined support 15 for the glass gathering ram 16 which is adapted to reciprocate radially of the machine. The ram is shown as provided with two gathering molds 17 so that two gathers may be made simultane ously. .Mechanism is provided for opening and closing the lower or swinging mold sections 18 and for )perating the cut-off knives 19 to remove the surplus glass from the molds after the gathers have been made. My present invention is not concerned with these mechanisms.

The ram is provided with a rack 20 which is in mesh with a pinion .21 keyed to a shaft 2; which is mounted in a housing forming part of the ram support 15, the ram being arranged so as to slide back and forth through this housing. In the upper part of the housing is mounted, for reciprocal movement, a slide it formed with a rack 35 adapted to mesh with a pinion 26 on shaft 22 of eonsiderably smaller diameter than pinion 21. ()n the top of slide it is pivoted an anti-friction roller 27 which is adapted to enter and pass. through, from end to end a slot 25. in a slide 35), the slot being formed in part by providing slide. 2) with pairs of projections 30, iii. as shown in Fig. 3. The

slide- 39 is engaged with a slide 32, the latter being provided with guideways 31) for the 'l'ormer, and the two elements bein normally held against relative longitudimfi a shoulder St on the upper slide 3:! and by a locking dog 35 pivoted between ears 30 on the lower slide 29 and held with its nose 3? in a notch upper slide by means of a coiled spring}? The machine provides mechanism for lis hgaging the upper aml lower slides, as shown in my said co-pending application 570,621, but such me .:hanism has no concern with the present invention. The two slides 29, 2&2 are provided so that, if desired, by disulgaging the dog 37 by means of manually operated connections. as explainedln my said co-pending application, the ram may be disconnected from its actuating mechanism. I For the purpose of this invention the elements 29, 32 may be considered as forming a single slide. This slide is moved in guideways 40 formed in a stationary structure, 41 by means of a rotating cam 42, the channeled eamway 43 of which engages an auti-friction roller H mounted on a stud 15 which projects through a slot 46 in the stationary structure 41. 1

Operation: It will be understood that the slide 29, 32 is arranged on a stationary structure at a point opposite the working opening of the furnace. The ram rotates uninterrupted-1y with the rotaryv structure 10. When the ram, in its movement of r'otation, reaches. a point opposite the working opening of the furnace, the roller 27 in slide 38 in the mice having a working openingo a rotary 115' 2t enters slot 28 of slide 29, 32. At the same time the cam channel 46 of rotating cam 42 takes inward bend, as a result of which slide 29, 32 is drawn inwardly toward the axis of the machine and with it slide 24. The movement of the latter slide rotates pinions 26, 21 and the latter being meshed with rack '20 on the rain, causes the ram to he thrust forward into the working opening of the furnace. The eam channel 43 of the rotating cam has an outward bend so placed as to etl'eet thewitlu'lrawal of the ram from the glass furnace as soon as the gather has beer made. The broken lines in Fig. 4 indicate the travel of the gathering molds on the end of the ram.

By means of the mechanism above described the ram is projected into and withdrawn from the furnace without a'nvcessation in its movement of rotation. 'Consel|uentl the gathering mechanism is considerably simpler than the mechanism diselosed in my mpendin" application above referred to. The ram, in continuing its rotation. as it approaches the position opposite the pot. is reeiprocated radially into and trout the pot. the roller 27 passing through the slot 98 while the slide 29-32 is being reeiprm-attal by the dip cam 42. The cam 1L2 rotates at a speed to repeat this operation whenever one of the rams comes opposite the pot.
